Family members look out for one another; if one becomes separated from the rest, the others search for it. The group adjusts its traveling pace to accommodate the old and the weak. The females within a family observe a strict hierarchical system. A dominant mare always leads the group, while others follow her in single file, each with their foals directly tennis behind them. The lowest- ranking mare is the last in line. Although the stallion is the dominant member of the family, he operates outside the system and has no special place in the line. Zebras are avid grazers. Both Burchell''s and Grevy''s zebras are in constant search of green pastures. In the dry season, they can live on coarse, dry grass only if they are within a short distance (usually no farther than 20 miles away) of water holes. Grevy''s zebras are now mainly restricted to parts of northern Kenya.

When a foal is born the mother keeps all other zebras (even the members of her family) away from it for 2 or 3 days, until it learns to recognize her by sight, voice and smell. While all foals have a close association with their mothers, the male foals are also close to their fathers. They leave their group on their own accord between the ages of 1 and 4 years to join an all-male bachelor group until they are strong enough to head a family. Zebras are important prey for lions and hyenas, and to a lesser extent for hunting dogs, leopards courts and cheetahs. When a family group is attacked, the members form a semicircle, face the predator and watch it, ready to bite or strike should the attack continue. If one of the family is injured the rest will often encircle it to protect it from further attack.

The larger Baringo or Rothschild''s giraffe (G.c. rothschildi) of western Kenya and eastern Uganda has chestnut patches separated by broader white lines but no spotting below the knees. This species can have up to five horns instead of the usual two or three. The Masai giraffe (G.c. tippelskirchi) of Tanzania and southern Kenya has irregular star-shaped brown or tan spots. Giraffes are found in arid and dry-savanna zones south of the Sahara, wherever trees occur. tennis Although a relatively quiet animal, the giraffe is not mute. Giraffes bellow, grunt, bray in distress, moan and emit short flutelike notes. They have acute senses of hearing and sight, often alerting other animals to nearby predators. Giraffes use a home range but are not territorial. The males are hierarchical and sometimes spar by standing side by side and lowering and swing their heads at one another. The blows can be so strong that their necks entwine.
